【発明の詳細な説明】
本発明は、防錆効果のある時計用外装部品に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exterior part for a watch that has a rust-preventing effect.
従来、金合金、パラジウム等のメツキを施した
時計用外装部品の材質は、洋白、黄銅等の銅合金
が主である。これらの銅合金を用いたものは上付
けメツキにピンホール、取扱い上のキズ等の欠陥
部分があると、そこから汗により腐食が進行しや
すいという問題があつた。 Conventionally, the materials for watch exterior parts plated with gold alloys, palladium, etc. have mainly been copper alloys such as nickel silver and brass. Products using these copper alloys had the problem that if there were defects such as pinholes or handling scratches in the top plating, corrosion would easily progress from there due to sweat.
本発明は、この問題を解決するもので、銅合金
用のインヒビターを添加したシリコングリースを
各部のパツキン部に塗布することにより、外装部
品の腐食を防止しようとするものである。 The present invention solves this problem by applying silicone grease containing an inhibitor for copper alloy to each packing part to prevent corrosion of the exterior parts.
銅合金系のインヒビターとしては、ポリリン酸
ヘキサメタ隣酸、ベンゾトリアゾール、トルトラ
イアゾール、2−メルカプトベンゾチアゾール、
2・5−ジチルカプトチアゾール、ベンズイミダ

ジオール等があげられる。これらのインヒビター
は、銅合金表面に、吸着する 酸化皮膜を形
成する 沈殿皮膜を形成する のうち1つある
いは2つ以上の効果を相乗させて腐食を防止して
いる。これらの効果を有するインヒビターを含む
シリコングリースをパツキンに塗布しておくと、
インヒビターが除々に汗中に溶解して、汗による
銅合金の腐食を防止する。 Examples of copper alloy-based inhibitors include polyphosphoric acid hexametaphosphoric acid, benzotriazole, tolutriazole, 2-mercaptobenzothiazole,
2,5-ditylcaptothiazole, benzimidazole, benzimidazole thiol, benzoxazole thiol, methylbenzothiazole,
Mercaptothiazoline, dithiocarbamic acid, thiosemicarbazide, 1.3.5 triazine 2.4
Examples include diol. These inhibitors prevent corrosion by combining one or more of the following effects: adsorption, formation of an oxide film, and formation of a precipitated film on the copper alloy surface. If you apply silicone grease containing an inhibitor that has these effects to the gasket,
The inhibitor gradually dissolves into sweat and prevents sweat from corroding the copper alloy.
シリコングリース中に重量比で0.2%未満では
充分な防錆効果がなく、5%をこえるとシリコン
グリス中に充分溶解しない部分が残るとともに、
これ以上加えても効果が向上することもなく、さ
らに、防錆剤の色による着色が大きくなる。 If it is less than 0.2% by weight in silicone grease, it will not have sufficient rust prevention effect, and if it exceeds 5%, there will be a portion that does not dissolve sufficiently in silicone grease, and
Adding more than this will not improve the effect, and furthermore, the coloration due to the color of the rust preventive agent will increase.
以上に実施例を示す。 Examples are shown above.
実施例 1
シリコングリース中に重量比で1%(0.2〜2

様な構造を有すると考えられている。Example 1 Silicone grease contains 1% (0.2 to 2
% of benzotriazole (practical) was mixed. This silicone grease was applied to the NBR case back cover and assembled into the body. After artificially making a scratch on the underside of this body so that the brass base came out, the scratched part did not change color at all even when it was immersed in artificial sweat at 40℃ for 24 hours. This is because some benzotriazole is eluted into sweat, and polymeric molecules are formed between Cu atoms and benzotriazole molecules. Therefore, the progress of corrosion due to sweat can be prevented. This polymeric molecule is thought to have the following structure.
実施例 2
シリコングリース中に重量比で2%(0.5〜5
%が実用可能)の2・5ジメチルカプトチアジア
ゾールを混入した。このシリコングリースを、
IIR製の裏ぶたパツキンに塗布し、胴に組み込ん
だ。これも、実施例1と同様に、人工汗40℃、24
時間の浸漬によつても全く変化を生じなかつた。 Example 2 2% (0.5-5% by weight) in silicone grease
% of 2.5 dimethylcaptothiadiazole (practical) was mixed. This silicone grease
It was applied to the back cover made of IIR and assembled into the body. Similarly to Example 1, artificial sweat was used at 40°C and 24°C.
No change occurred even with time immersion.
以上の通り、シリコングリース中に銅合金用の
インヒビターを溶かし、これをパツキンに塗布す

返し行うことにより、嵌合部が磨耗して銅合金が
露出しても、インヒビターにより防錆効果、シリ
コングリースにより撥水効果を同時に重複させて
もたせることができる。 As mentioned above, by dissolving a copper alloy inhibitor in silicone grease and applying it to the gasket, it is possible to remove the back cover of copper alloy-based watch exterior parts, for example, to replace the battery. By repeating this process, even if the fitting part is worn and the copper alloy is exposed, the inhibitor can provide a rust-preventing effect and the silicone grease can provide a water-repellent effect at the same time.
また、嵌合部はメツキなどをした場合、メツキ
液中の気泡がたまつてピンホールが発生しやすい
こと及び常に外から汗や海水などにより腐食の危
険にさらされているが、前述の重複させた撥水と
防錆の効果により、安心した時計用外装部品を提
供することができる。 In addition, when the mating parts are plated, pinholes are likely to occur due to the accumulation of air bubbles in the plating liquid, and they are always exposed to the risk of corrosion from outside, such as sweat and seawater. The water-repellent and rust-proofing effects make it possible to provide reliable exterior parts for watches.
